Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed October 27, 1911. Serial No. 657,155.

To all whom it may concern:

Be it known that I, FREDERICK HENRY ROYCE, a subject of the King ofGreat Britain and Ireland, residing at Nightingale Road, Osmaston Road,Derby, in the county of Derby, En land, have invented certain new anduse 111 Improvements in Transmission-Gearing for Motor Road- Vehicles,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to that type of transmission gearing for motorroad vehicles in which the road wheels are mounted on a fixed tubularaxle within which the driving axles run, and in which the drive from thepropeller shaft to the driving axles is through bevel gearing, andparticularly to that type in which provision is made for adjusting theposition of the bevel wheel in relation to the bevel pinion for thepurpose of correctly setting the meshin of the teeth of said wheels, andit has for its object obtaining said adjustment in either direction by asingle operation and in a more simple and convenient manner than hashitherto been possible. I attain this end by combining with the bearingadapted to take the thrust of the bevel wheel a second surface orbearing adapted to retain the bevel wheel in an axial direction oppositeto the thrust and by mounting the combined hearings in a housing whichis capable of adjustment in either direction axially in relation to thefixed axle or casing.

In the accompanying drawing which shows one method of carrying thisinvention into practice :'Figure 1 is a broken view in planpartly insection-illustrating this invention, and Fig. 2 is an enlarged viewthereof.

In both views similar parts are marked with like letters of reference.

The cage n carrying the differential gearing d is as usual mounted overthe inner ends of the two-part driving axle o and is supported inbearings w carried by the box or case 2 within which the bevel drivinggearing m 0 and differential gearing d are located, the cage n beingcapable of sliding axially relatively to the inner races of the saidmain bearing carrying with it the differential gearing bevel wheel andtwo parts of the driving axle, said parts being free to move axially andrelatively to the road wheels by means of the usual sliding driving jawsor keys arranged in the hubs of said road wheels. The one part p of thethrust bearing is mounted in a sleeve or housing 9 which is adjustablymounted by means of a screw-thread in a sleeve-like extension 1' formedon or carried by the interior 2 of the box a, said sleeve or housingbeing capable of being locked to the sleeve-like part 7* of the axle box2 by means of any suitable locking device such as the finger 7" which ismounted on the sleeve 9. The other part 8 of the thrust bearing ismounted on the boss n of the differential cage so that it revolves withit, said cage being kept in position thereon by a ring a threaded on thesleeve n and locked thereto by any suitable locking device. Abuttingagainst the back or outer face of the part 8 of the thrust bearing is acollar t which is adj ustably mounted in the interior of the sleeve q.

. In order to adjust the beveled toothed wheel m longitudinally on theshaft '0, the locking finger 7' is first removed, and the screw threadedhousing 9 is then revolved in the screwthreaded sleeve r, so as to movethe two opposed thrust-bearing members 1) and s to the right or to theleft, as required, thereby sliding the cage 02- together with thedifferential gearin inclosed in it and the beveled toothed w eel m. Thehousing (1 is revolved b hand or by any suitable wrench applie to theteeth What I claim is:

1. The combination with a support or casing provided with bearings andhavin a screwthreaded sleeve, a cage for the dierential gearing mountedin the said bearings, and a beveled toothed wheel secured to the saidcage; of a revoluble screwthreaded housing engaging with the saidscrewthreaded sleeve, a thrust-bearing carried by the said housing andhaving one of its parts connected to the said cage, and a locking devicewhich normally prevents the housing from being revolved in the saidsleeve.

2. The combination, with a support or casing provided with bearings andhaving a screwthreaded sleeve, a cage for the differential gearingmounted in the said bearings and provided with a hub, and a beveledtoothed wheel secured to the said cage; of a revoluble screwthreadedhousing engaging with the screwthreaded sleeve, a thrust- In testimonywhereof I have signed my bearing carried by the said housing, a, ringname in the presence of two subscribing Witscrewed on the said hub andsecuring one nesses.
